Magnetic Knee Support Sleeve - 32 Magnets

Magnetic Knee Support Sleeve | 32 North-Polarity Magnets for Natural Knee Comfort

Dr. Sierra Magnets™ — Wearable Biomagnetic Therapy for Active Daily Life

Your knees carry you through everything — every step, every climb, every moment on your feet. The Dr. Sierra Magnets™ Magnetic Knee Support Sleeve wraps 32 strategically placed north-polarity (negative) magnets around the entire knee area, delivering consistent biomagnetic therapy while you move through your day. No straps. No bulk. No interruption to your routine.

Slip it on. Go about your day. Let the magnets work.

What Makes This Sleeve Different

Most knee sleeves offer compression only. This one combines compression with 32 individual 1,000 gauss north-polarity magnets — each positioned with the Bio-Negative (North) pole facing the skin, consistent with Dr. Sierra’s biomagnetic therapy protocol. The result is full 360° magnetic coverage around the knee — while remaining thin enough to wear under clothing or to sleep in comfortably.

The Science Behind Static Magnets & the Knee

Static magnets like those in this sleeve do not use electricity — they create a steady, passive magnetic field around the joint. A major 2005 clinical review concluded: "The weight of evidence from well conducted trials suggests that static magnetic fields are able to induce analgesia (pain relief)." Out of the better-quality studies reviewed, 11 out of 15 showed that static magnets helped reduce pain — including musculoskeletal and joint pain conditions.

• In animal studies, moderate-strength static magnets reduced swelling (edema) by approximately 20–50% when applied after an injury, by influencing how tiny blood vessels behave.
• Some reviews suggest static magnets may help normalize blood vessel tone in local tissue — supporting microcirculation in the area where the sleeve is worn.

How to Use

1. Measure your knee circumference and select the correct size (see guide below).
2. Pull the sleeve up over the knee so it sits centered over the kneecap.
3. Wear during daily activities, exercise, extended periods of standing and walking, or overnight while sleeping.
4. Can be worn under additional supports, braces, or clothing.
5. For best results, wear consistently as part of your daily wellness routine.

Size Guide

How to Measure: Measure the circumference of your knee 4" above the center of the kneecap while standing with your leg slightly bent. Match your measurement below.

• Large — 17" to 19" (43–48 cm)
• X-Large — 19" to 21" (48–53 cm)
• 2X-Large — 21" to 22½" (53–57 cm)

❓ Frequently Asked Questions

How is this different from a regular compression knee sleeve?
A standard compression sleeve supports the joint mechanically. This sleeve adds 32 north-polarity magnets positioned around the entire knee — combining compression with passive biomagnetic therapy for a more complete approach to knee wellness.

Can I wear it all day?
Yes. The breathable, stretchable fabric and pull-on design make it comfortable for extended daily wear — during activities, work, or rest.

Can I sleep with it on?
Yes! The sleeve is comfortable enough to wear overnight. Many users choose to sleep with it on to allow the magnets to work continuously through the night — especially helpful for those who experience nighttime knee stiffness or discomfort.

What does “north-polarity” mean?
In biomagnetic therapy, the north (negative) pole of a magnet is used for its calming, normalizing effect on tissue. All 32 magnets in this sleeve face North toward the skin — consistent with Dr. Sierra’s biomagnetic protocol.

Can I wear it under clothing or a brace?
Yes — the sleeve is thin enough to wear discreetly under pants or layer beneath an additional knee brace or support.

How do I know which size to order?
Measure the circumference of your knee 4" above the center of your kneecap while standing with your leg slightly bent. Match that measurement to the size guide above. Not sure? Call us at 787-782-5767 and we’ll help you find the right fit.

Is it safe to use with medical devices?
Do not use near pacemakers, defibrillators, or transdermal drug patches. Consult your healthcare provider before use if you have any implanted devices or medical concerns.
